FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering. Method of electric arc fault detection is intended for detection of electric arc fault with control of optical radiation.
EFFECT: high noise immunity is carried out by counting the number of optical flashes over a given time with subsequent comparison with a threshold value and when the threshold for making a control action is exceeded.
